Specification of Letters Patent.

Patented July 15, 1913.

Application filed June 11, 1912. Serial No. 708,043.

To all whom it may concern:

Be it known that I, IRA A. MANN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Plumbing-Fixtures, of which the following is a specification.

The invention relates to plumbing fixtures, and particularly to connections for what are known as wall outlet fixtures, that is, fixtures hung or supported from the wall or against the wall, as opposed to those in which the support is from the floor. The invention is illustrated as applied to a closet, but it will be understood that the construction is applicable to all kinds of plumbing fixtures employing bowls ,or receptacles. This application is in part a continuation of my prior application which has matured into Patent N 1,017,437. The invention has for its principal objects; the provision of a construction having an improved form of joint .connection between the bowl and outlet pipe, or soil pipe as it is termed in the art; the provision of a joint connection of the character specified which can be adjusted and made absolutely tight with a metal contact; and the provision of an improved joint construction which shall be of great strength and rigidity, so that if desired the entire weight of the bowl may be supported directly from the soil pipe by virtue of this rigid joint connection. Certain embodiments of the invention are illustrated in the accompanying drawings,

wherein Figure 1 is an assembled view in section through the joint connection and illustrating the manner of supporting the bowl upon the coupling and against the partition, Fig. 2 is an enlarged sectional view of the end of the soil pipe with the coupling therein, Fig. 3 is a section through a modified form of joint connection, Figs. 4, 5 and 6 are detailed views of the joint construction of Figs. 1 and 2, Fig. 4 being a section through that portion of the joint connection lying inthe bowl, Fig. 5 being a. side elevation of the coupling member, and Fig. 6 being a lan view of the construction as shown in i 4. Figs. 7 and 8 are detail views of a too which may be employed in positioning thecou ling or coupling member shown m i 7 being a section throu h the tool, and

ig. 8 being an end view t ereof,

Figs. 9, 10 and 11 12 are detail views of a modified form of joint construction, Fig. 9 being a section through the annular member secured in the bowl, Fig. 10 a side elevation of the coupling, Fig. 11 a section through the tool employed in positioning the coupling and Fig 12 an end view of the tool of Fig. 11, Figs. 13, 14, 15 and 16 are detail views of still another modified form of joint connection, Fig. 13 being a section through the joint member in the bowl, Fig. 14 being a side elevation of the coupling, Fig. 15 being an end View of the construction of Fig. 13, and Fig. 16 an end view of the coupling of Fig. 14. Figs. 17, 18, 19 and 20 are etail views of another modified form of joint construction, Fig. 17 being a section ,through the joint member in the bowl, Fig.

18 being a side elevation of the coupling, Fig. 19 being an'end view of the joint member of Fig. 17, and Fig. 20 being an end view of the coupling member of Fig. 18, and Figs. 21 and 22 are longitudinal sections through other modified forms of joint construction.

Referring to Figs. 1, 2, 4, 5 and 6, 1 is the bowl of a Wall closet havingan outlet passage 2 and resting in position opposite a partition 3; 4 is a soil pipe located back of the partition 3 and having a vent pipe 5; 6 is what may be termed a bearin plate, which bearing plate is secured to t e wall and piping and assists in supporting .the bowl in the manner illustrated, such bearing plate construction being more particularly shown and described in my application Serial No. 667,313, filed December 26, 1911; 7 is an annular joint member rigidly mounted in the bowl at the outer end of the outlet passage 2; and 8 is a coupling or coupling member secured at one end in the annular member 7 and at the other end in the outlet or soil-pipe 4.

The construction of the joint member 7 will be apparent from Figs. 4 and 6. This joint member is of metal and is seated in an enlargement at the outer end of the outlet passage 2, lead or other similar packing 9 being inserted between the side of the annular member 7 and-the interior surface of the said enlargement. The joint member 7 is provided with lugs 10 (Fi 6) to prevent the rotation of the member and provide an enlarged support for the packing thereabove, the enlargement in the bowl being correspondingly cut out to receive such lugs as indicated in Fig.6. The member 7 is provided a with the inclined grooves 11 adapted to receive the lugs 12 earned by the coupling member 8 and the member'7 is also provided with a'beveled portion 13 corresponding to the beveled portion 14 of the coupling'8, the arrangement being such that apartial rotation of the member 7 with respect to the member 8 will cause the beveled surfaces 13 and 14 to be forced tightly to ether. The inclination of the grooves 11 1s such that only a fraction of revolution of the bowl and the member 7 carried thereby is necessary in order to bring the beveled surfaces tightly together. T is is advantageous, as in some cases it is not possible to give the bowl a full revolution because of the interference with the floor. The lugs 12 and grooves 11 constitute an interrupted quick screw connection. The outer portion of the coupling 8 is screw-threaded into the end 15 of the soil pipe as indicated in Fig. 2 and is locked in position by means of a nut 16 which fits into a recess in the end of the part 15 as indicated in Fig. 2. This nut 16 is of a relatively soft packing material such as lead and screw threaded to fit the threaded portion of the coupling 8, and after the coupling member 8 has been brought to its proper position this packing nut 16 can be screwed down to position and tamped tightly into position, thus making an absolutely tight oint between the soil pipe and coupling and prevents any rotation of the coupling with respect to the soil pipe when the bowl is screwed onto the other end of the coupling. The provision of the packing 16 in the form of a nut constitutes a convenient means for positioning such packing, but if desired the packing might be poured into the recess while hot, or positioned in any other desired manner.

The tool shown in Figs. 7 and 8 can be utilized in adjusting the coupling member of its proper position in the soil pipe. This tool 17 is provided with a head 18 for engaging a wrench and has upon its interior a beveled surface 19 corresponding to the bevel 13 on theannular member 7 and also has grooves 20 corresponding to the grooves 11 on the annular member 7. When the tool 17 is screwed upon the end of the coupling 8 and such coupling 8 is screwed into the soil pi e until the flange 21 on the tool comes ush with the outer face of the partition, the position of the coupling 8 is fixed and if the tool is then removed and the bowl secured in position its bearing face will fit against the partition when the surfaces 13 and 14 of the annular member 7 and coupling come together. The tool is provided with a mark- 22 which serves to indicate the proper rotative position of the lugs 12. When the coupling 8 has been screwed to its proper position in the soil pipe the packing memes nut 161s securely tamped into position thus preventing any further rotating of the coupling in either direction and providing a tight joint between the coupling and soil pipe. The coupling member is thus accurately and rigidly secured in its proper position of adjustment.

In the construction shown in Fig. 3 the annular joint member 23 is maintamed securely in position in the bowl by means of the lead packing 24 and a tight joint is secured between the coupling 25 and the member 23 by means of the packing ring 26 of lead or other suitable material which 1s compressed against the member 23 and against the coupling 25 by-the ring 26, such ring 26' being pulled inward by means of the studs 27. The sides of the packing ring 26 are inclined and a notch provided in the outer face in order to secure a more ready crowding inward of the acking when the ring 26' is drawn inwar by the studs 27.

.The end 15 of the soil pipe is connected to the end of the coupling 25 in the manner heretofore described, the nut 16 being of packing material.

Figs. 9 and 10 illustrate another form of construction which may be employed in lieu of the construction shown in Figs. 4, 5 and 6. In this construction the interior of the joint member 28 which is secured in the bowl is provided with ordinary screw-threads 29 with which the screw-threads 30 on the coupling member 31 cooperate, the ordinary continuous screw connection thus taking the place of the interrupted quick screw connection of the structure of Figs. 4, 5 and 6. The coupling 31 is moved to position by means of a tool 32 corresponding in function to the tool 17 of Figs. 7 and 8, such tool having upon its interior threads 33 adapted to fit the threads 30 of the coupling 31.

The coupling illustrated in Figs. 13, 14 and 15 is quite similar to that of Figs. 4, 5 and 6, the primary difference being in the use of an ordinary nut 34 which is provided upon the coupling member 35 instead of the packing nut 16 of the construction of Fig. 2, such nut 34 being adapted to screw against the end of the soil pi e. Another feature of distinction in this orm of connection as compared with the construction of Figs. 4, 5 and 6 resides in the placing of the beveled portion 36 in advance of the lugs 37 which is the reverse of the arrangement shown in Figs. 4, 5 and 6. The lugs 37 in this construction cooperate with the slots 38 and serve to draw the beveled surface 36 tightly in engagement with the beveled surface 39 on the annular joint member 40.

The annular joint member 40 is provided.

with lugs 41 corresponding to the lugs 10 shown in Fig. 6 and the member 39 is secured in position in precisely the same mannor as the member 7 of Fig. 4. The nut 34 not onl serves to make a tight joint between t e coupling 35 and the soil pipe but also tends to prevent rotation of the coupling member with respect to the soil pipe.

In order to still further guard against the rotation of the coupling member 35, its outer surface is grooved as indicated at 41 and in these grooves are fitted keys 42. -After the coupling 35 has been screwed to position these keys are driven down in the grooves and cut into the threads on the soil pipe thus effectually preventing rotation of the coupling.

. Figs. 17, 18, 19 and'20 illustrate still another form of joint. In this construction an ordinary quick screw connection is provided between the coupling 43 and the annular member 44, such quick screw connection comprising the series of threads 45 engaging corresponding grooves 46 in the member 44. The coupling 43 is also provided with a beveled surface 47 adapted to fit against the end of the member 44 when the coupling is secured into position.

Fig. 21 illustrates a construction quite similar to that of Figs. 17, 18, 19 and 20 the primary 'diflerence being that the beveled surface 48 on the coupling 49 is in advance of the screw-threads 50.

In the construction of Fig. 22 the ground joint 51 is in advance of the screw threads and recessed portions 52 alternate with sets of interrupted threads on the coupling member 54. The annular member 55 with which the coupling cooperates is of course correspondingly formed so that. the coupling member can he slipped up inside the joint member and by a fraction of a rotation, the ground joint portions of the connection are brought tightly into contact. This form of joint can be very cheaply made as little machine work is necessary.

Having thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following:
